Nintendo Switch BOTW framerate vs. temperature

20180324 Korok Forest (day)
This scene was chosen as frame drops are noticeable and it is graphically intensive. This should expose thermal throttling if it is taking place.
Both captures were taken using the same methodology:
1. Load save and wait until shrine text disappears.
2. Begin recording.
3. Sprint in front of the master sword pedestal, turn around at the rock on the far side, run past the deku tree and back towards the shrine, sit at the shrine for 1-2 seconds.
4. Stop recording.
Recording was done with an iPhone 6S plus capturing 720p240 using beer cans and boxes to prop up. auto focus and auto exposure was locked.

test setup and fan location

20180323 Goron City
Drop in temperature is from turning on fan
The stems are when video data was taken. A combination of bad camera placement/settings, the use of goron city, the use of standing idle, and LEDs in the room with a refresh rate as a multiple of 120 Hz caused this data to be bad.
This plot is included to show the effect of the fan.
